Abstract top

The title complex, [Ag2(C10H8N2)2(C32H30N2P2)](ClO4)2·2CH3COCH3, is a centrosymmetric dimer with pairs of AgI atoms bridged by N,N'-bis(diphenylphosphinomethyl)benzene-1,4-diamine ligands. In addition, each AgI atom is coordinated by one chelating 2,2'-bipyridine ligand, giving a distorted trigonal coordination environment.

Comment top

There has been great interest in d10 metals complexes containing diphosphine and polypyridyl ligands because of two main reasons: the first is diphosphine ligands effectively stabilize low-valent d10 metals complexes due to their electronic and steric characteristics (Meijboom et al., 2009; Ogasawara et al., 2000), and the other is the chelating polypyridyl ligands such as 2,2'-bipyridine and 1,10-phenanthroline (phen) are present of low-energy orbitals, the adducts always exhibit strong Ligand-metal charge-transfer (LMCT) or Metal-ligand charge-transfer (MLCT) absorption bands in the visible spectrum (Armaroli, 2001). In the past, we have obtained a series of AgI and Cu(I) complexes containing both diphosphine and chelating polypyridyl ligands, from which we found that these complexes all exhibit interesting photoluminescent properties at low temperature or even at room temperature (Wang et al., 2008). Here we report the crystal and molecular structure of[Ag2(C10H8N2)2(C32H30N2P2)](ClO4)2.2CH3COCH3, (I). This work complements and extends our structural characterization of d10 metals complexes containing diphosphine and polypyridyl ligands.

Diphosphine ligands effectively stabilize low-valent d10 metals complexes due to their electronic and steric characteristics, see: Meijboom et al. (2009); Ogasawara et al. (2000). Adducts of chelating polypyridyl ligands such as 2,2'-bipyridine and 1,10-phenanthroline (phen) always exhibit strong ligand–metal charge-transfer (LMCT) or metal–ligand charge-transfer (MLCT) absorption bands in the visible spectrum, see: Armaroli (2001). For a series of AgI and Cu(I) complexes containing both diphosphine and chelating polypyridyl ligands which exhibit interesting photoluminescent properties at low temperature or even at room temperature, see: Wang et al. (2008). For the synthesis of N,N-bis[(diphenylphosphino)methyl]-benzene-1,4-diamine, see: Durran et al. (2000); Hellmann et al. (1962). For related structures, see: Effendy et al. (2007); Zhang et al. (2003).

Experimental top

The synthesis of (I) was carried out by the reaction of AgClO4.H2O (0.045 g, 0.2 mmol), 2,2'-bipyridine (0.032 g, 0.2 mmol) and N,N-bis[(diphenylphosphino)methyl]-benzene-1,4-diamine (0.0504 g, 0.1 mmol, synthesized according to literature (Durran, et al., 2000; Hellmann et al., 1962) in acetonitrile-acetone (7 ml with a ratio of 4: 3) solution, the resulting orange red solution was allowed to stir for 0.5 h at room temperature.Then by slow diffusion of diethyl ether into the solution, block red crystals were formed suitable for X-ray diffraction analysis.

Refinement top

All hydrogen atoms were generated geometrically with C—H = 0.95-0.99 Å and N—H = 0.88 Å, and refined with a riding model [Uiso(H) = 1.2Ueq(N,C)]. The highest residual peak is located 0.49Å from atom Ag1 and the deepest hole is located 0.55Å from atom Ag1.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
